The spiral shape lessens wind noise created by typical cylindrical shaped antennas masts. It is there for passenger compartment noise reduction only, and has nothing to do with the noise or clarity of the radio signal it receives.
use a stronger wire for longer antennas...the gauge may not be as important as the strength if you string it outside.
It is. Grounding your shortwave radio is important for a couple reasons: Many antennas that are used on shortwave radio perform correctly ( or better ) when a ground is established. ( Marconi Antenna ). Verticle antennas also use a ground wire as a " Counterpoise". The more radials used, the better RF resistance. Grounds can help the S/N raio as well by elminating some of the RF hash. Also, a Lightning arrestor is very important in case of a lightning strike. Good luck.
same way you'd wire a radio in any other car.
Yes. In fact, Bose offers its own "add-on" antennas for about $10 each that plug into the back of their radios. These are simple dipoles -- T-shaped wire, with the arms about 2 feet long and a longer center wire with a connector on the end. Similar antennas are available from other vendors too. Be aware that depending on when you bought the Wave radio, it may have either a standard F connector or a 1/8 inch minijack on the back for antenna connections -- make sure you get the right one. And yes, you can plug a more sophisticated indoor or outdoor antenna into the same jack. With any antenna, its effectiveness depends on where you locate it. An outdoor antenna has to be pointed in the general direction of the radio station(s) you're trying to receive for best performance. Indoor antennas are highly affected by location and position. You'll have to move them around to find the best location. With a little experimentation you should get a much stronger, cleaner signal than the built-in antenna provides.
Don't know the color of the wire but you will just have to use a test light to see what wire is hot to the radio.
Plastic wrapped around the wire is insulator. Not a conductor. That is why it is wrapped around the conductor wire.

Well, it CAN be wrapped either way, but because standard screws tighten when turned clockwise:if the wire is wrapped around the screw clockwise tightening the screw will pull the wire tighter around the screwif the wire is wrapped around the screw counterclockwise tightening the screw will push the wire away from the screw making it loose and maybe even popping the wire out from under the screwSo, if you want the wire to stay secure on the screw only wrap it clockwise!
A solenoid. An electromagnet is wire wrapped around a core of iron (usually). The wrapped wire itself is called the solenoid.
electromagnet
The strength of an electromagnet depends on: -- The magnitude of the current through the wire. (This depends on the voltage between the ends of the wire.) -- The number of turns of wire in the coil wrapped around the iron core.

Coils of wire wrapped around a ferromagnetic core make up a motor's armature. It carries an electrical current and rotates within a magnetic field.
